摘要: 用500MHz超导核磁共振谱仪测定了甲基丙烯酸甲酯-萘乙烯共聚物的二维异核多量子化学位移相关谱和二维相敏NOESY谱,由此归属了共聚物的碳谱和氢谱,结果表明,聚合物是以无规共聚物为主,其中有一部分是以头-头(或尾-尾)相接的.文中还以反门控去偶测得其共聚含量.

Abstract: Methyl methacrylate-naphthyl ethylene copolymer was studied by two dimensional NMR spectroscopy (2D H, X-COSY, NOESY). 13C and 1H chemical shifts of the copolymer were assigned (Tab.2). Results show that the structure of the copolymer is mainly random with respect to the stereochemical configuration, there are some head-head (or tail-tail) copolymers linked by methyl methacrylate and naphthyl ethylene. The content of copolymers was measured by inverse gated heteronuclear decoupling.
